** sql variables
   :PROPERTIES:
   :DATE:     2010-11-30
   :END:
#+name: sql-param
| table       | valueTable0       |
| column      | valueColumn0      |
| type        | valueType0        |
| nullability | valueNullability0 |

I want to apply the values onto the following chunk of code:

#+name: add-column-in-table-0
#+begin_src sql :var table=sql-param[0,1] :var column=sql-param[1,1] :var type=sql-param[2,1] :var nullability=sql-param[3,1]
-- add column `@column' (if column does not exist yet)
IF NOT EXISTS (SELECT *
               FROM INFORMATION_SCHEMA.COLUMNS
               WHERE TABLE_NAME = '@table'
               AND COLUMN_NAME = '@column')
BEGIN
    ALTER TABLE $table
    ADD $column $type @nullability
END
#+end_src
